Advantage: By moving around inside the cell, chloroplast can reorient itself in order to expose to the maximum of the sunlight necessary for the photosynthesis.
Disadvantage: Movement <span>around</span> of the chloroplast inside of the cell requires energy. The cell can produce energy, but the energy is needed for other processes of the cell.
Lunar eclipses are more widely visible because Earth casts a much larger shadow on the Moon during a lunar eclipse than the Moon casts on Earth during a solar eclipse.
Answer:
Explanation:
1. a. Interphase is the phase of the cell cycle in which a typical cell spends most of its life. During interphase, the cell copies its DNA in preparation for mitosis.
b. The third phase is anaphase. This phase only takes about 0.8 percent of the cell cycle to complete, which is the shortest time required out of all the phases. During anaphase the sister chromatids, or the two identical parts of a chromosome, are pulled apart to opposite ends of the cell by the spindle fibers.
2. Mitosis is important for three main reasons: development and growth cell replacement and asexual reproduction.
- Development and growth. After meiosis has produced a gamete, and this has fused with another gamete to form an embryo, the embryo grows using mitosis. ...
- Cell replacement. ...
- Asexual reproduction.
Hippos are being endangered mainly because the poachers hunt them for their meat and their ivory teeth
